About cutthebill

Sun On Tap started because the UK energy space had a problem. Too many sites either talk down to people or quietly push them toward whatever product pays the biggest commission. We wanted something different — a place where normal homeowners and renters could get straight answers without wading through jargon or sales copy dressed up as advice.

We cover the full picture. Plug-in solar is where most people start — it's affordable, it's finally legal, and you can have it running this weekend. But we also cover smart tariffs like Octopus Agile, full rooftop solar systems, heat pump grants, battery storage and everything in between. Whatever stage you're at, there's a logical next step and we'll help you find it.

Everything here is written by someone who's actually built this stuff — solar arrays, off-grid systems, Home Assistant automations, the lot. We analyse the regulations, test the numbers and keep up with every policy change so our readers don't have to. No fluff. No agenda. Just the clearest possible path to a lower energy bill.
